A bounty of three million Turkish lira, or nearly $800,000, was placed on the heads of former Pentagon official Michael Rubin and former top CIA official Graham Fuller for what Erdogan’s allies claim is their role in a 2016 failed coup that nearly toppled Erdogan’s ruling government.

Both Rubin and Fuller have been vocal critics of Erdogan’s, often publicly highlighting his widespread corruption. Rubin, in particular, has been in constant conflict with Erdogan, who once filed a lawsuit against the former Pentagon official in a bid to silence him.

The Turkish prosecutors office has issued arrest warrants for both Rubin and Fuller.
